UNITED STATE s PATENT? orifice JAMES n. commu, or PLEASANT RIDGE, MICHIGAN.

mmnNnL-ooitws'rion ENGINE Application flied May 8,

To all 'whom lt may concern.

Be it known that LJAMES R. QUINLAN, e citizen of the United States,1ind residing in the village of Pleasant Rid'gdin the county of Oakland 11nd Stute of Michigan, lieve invented new and vuseful Improvements in an Internal-Combustion Engine, of which the following is a' specification. Y rElie object of my invention is to provide improvements engine, of simple, durable, and inexpensive constructionx A further object of ii'iy invention isv tor with the teeth on :i moving part of the engine such, :tor instnnceins the fly wheel, the engaging device. being current is supplied' to the motor then that the engaging device will iiiitometiWV ly engage the teeth mentioned. but when the engine starts running under its own power then the teeth will be disengaged.

`A further object ot my invention is to .rovide such iin engaging device with menne or automatically moving an engaging' pinion along :i shaft when the parte associiited therewith are rotated, this movement heine; Vocconiplished hy the inertia. of the pinion and the functions of the parte essoci ated therewith A. further object ot my invention is to 'provide Ineens assoeieted with such ongegirig device aiidpinion to 'form ii yielding connection between the engr giiig'ilevicc find pinion both for the purpose oi cushioning the shock of engagement, and also for 'the purpose of forming :in :iiitoniiiticvslippage device in case the engine hficlttires.

A further object of my invention is to rovide yielding means 'for automatically holding the pinion out otl engzigeinentivitli the teeth o n vthe engine whenthe pinion is' in inoperative `position.

A further object of my invention is to in an internal combustion.

so arranged that when i922. seri'ai No. 559,129.

provide a novel form of cam device for utilizing theinertia of the pinion and. parte associated therewith for .moving the` pinion into and outof engagement. A. i I

A further object `ot' my invention is to provide an association of parts in connection with the slippage device mentioned and the cam device mentioned whereby movement of the pinionin a direction causing it to engage ,teeth on the engine, this movement being caused bythe cam device, wili in turn affect the slippage device to regulate the slippage permitted thereo In this connection itr may be Irientionedy that this feature is kdesigned for the purpose of' eliminating the necessity for adjusting ,the tension or bearing otv the slippzigedevice from time to time..

i further object of 'my inventionis to provide e device wherein the drivin pinion will not form n driving connection etween the starting motorend engine until the teeth of the pinion. are `*fully engaged .with the teeth, associated with the engine, lso that y there may be no undue strain on tlievteeth ofeither the pinion or engine.

A Jfurther olfectol my invention isto provide a clutch device of the type known ns o "multiple disc clutch which may he interposed between the cngfiging pinion and the motor shaft thereby se'ciiringithe necesser); cushioning end:- slippege between lthe motor shaft end the engine. j

i'lith these 'and other objects in View,` my invention tonsists inthe arrangement/conihinntion, and construction ot the vniioiis parte .of niyiniproved device, es described in the specification; claimed in .my claims.y :end shown in the accompanying drawings, in

which:

Figure l shows a side elevation or en intermal combustion engine having a. transmission associated therewith, aetertingmotor, end :in engaging device, parte being broken 'to better illustrate the construction.

Figui-e Si shows an elevation of the engaging device illustrated in 'Figure 1, parte tl'iereoi being tion to better illustrate the construction. Figure 3 shows en eiid elevation of the de vice illustrated in Figure 2.

Figure 4c shows an end view off the engaging; device. l l i Figure 5 shows a sectional view teken on the line 5--5 of lFigure 2. i I

Figures 6, 7, ,8, and 9, show detail views nally. After the engaging device has been disassembled from the shaft it is possible to disassemble the gear 19 from the device and with it the clutch portion thereof by simply uri-twisting the Wire 604 which Will permit the screws 27 to be loosened so that the gear 19 may he withdrawn and thereb permit access to, or removal. of the clutc portion of the device. It will, therefore, be seen that l have provided a structure, which may he readily assembled or disassembled, of unitary formation, and which is not at all likely to get out of order; and, if for any reason it should get out of order, then that it may he easily repaired.

I have also provided means for automatically engaging the longitudinally movable portion of my improved device for locking it in inoperative position, so that it Will not accidentally become engaged with the teeth on the fiy Wheel. Even, however. assuming that such engagement should occur. it Will be seen that the clutch members will slip as there will be no pressure caused by the torque of the starting motor to force these clutch 'members together to form a positive connection between the gear 19 and the shaft 16.

Some changes may be made in the arrangement and construction of the various parts of my improved device Without departing from the spirit of the invention disclosed therein. and it. is my intention to cover by my claims such changes as may be refasonably included Within the scope thereo I claim as my invention:

l. In a device of the character described, a starting motor having a shaft extended therefrom, a sleeve secured to said shaft, a second sleeve floated on said shaft, an engaging device floated on said shaft, means for operatively connecting said second sleeve with the engaging device adapted to form a driving connection which will permit unlimited slippage therebetween when a maximum load has been placed thereon, and means for connecting said firstl and second sleeves whereby movement of the shaft combined with inertia of the parts associated with the second sleeve will cause movement of said second sleeve and the parts associated therewith longitudinally of said shaft. 2. In a device of the character described, a starter motor having a shaft extended therefrom, a sleeve fixed to said shaft, a second sleeve floated on said shaft, van engaging device floated on said shaft` means for operatively connectingr the first and second sleeves whereby imparting rotation to the shaft Will cause the float sleeve to move longitudinally relative to the shaft` means for operatively connecting the engaging device and said floating sleeve whereby the engaging device is normally held from rotation relative to the second sleeve by a rela-- tively light resistance, said first mentioned means being adapted to increase said resistance automatically to the torc. capacity of the motor when the sleeve and engaging device have reached a predetermined position. said means permitting slippage When the tore capacity of the motor is exceeded.
